The present invention relates to a composite fabric wherein a plurality of
small tows are intermittently spaced between large tows forming channels.
The channels formed by spacing the between the large tows thereby forming
ridges. The irregular thickness that results from the ridges provides
flow channels during resin infusion of the fabric. The flow channels
permit resin to flow evenly and quickly through the fabric, which results
in shorter processing time and a more consistent resin distribution,
decreasing the likelihood of resin starved areas within the cured
